Thank you very much for your detailed reply and I'm assuming your are under quite a blanket of snow at the moment!

My troubleshooting steps did not get very far...

...following the Channel Master troubleshooting instructions, I disconnected the the coax from the power inserter that goes to the amp. I then used a multimeter and connected on lead to the center pin on the coax and then the other lead to the metal casing (set the coax to volts..."20" max). There was no read out. So I then disconnected the DC-IN (powered) coax from the power inserted and used the same method to test the voltage. Voila! There was a read out (ranged from 18 - 20 volts or so). This tells me the power coax is distributing power, but that current is not flowing out of power inserter at the AMP end. According to Channel Master, this indicates a faulty power inserter.

My question is this: I have read that certain amps don't need power inserters, but I think the 7777 requires a power inserter. Am I correct?

My next question (this is born of my desire to get this working before tomorrow): Is there any work around given that I don't see how I'd get a replacement in time? Are there any generic power inserters that I might find at a local store?

Thanks again in advance!
